f -Laim Patent No. 85,1525.

lated-December 22, 186s.

IMPEovED COOLER Eon WATER, MILK, AND OTHER LIQUI'Ds.

The Schedule referred tointhese Letters Patent and z'naking part of the same.

To all whom it 'may' concern Beit known that l, HERMAN Prnrscn, ofthe city, county, and State. of N ew York, have invented a .new "and improved Gooler for-Water, Milk, 86e. ;l and I do herebydeclae that the following is'a full, clear, and exact4 description thereof, which will enable others skilled inthe art to make and use the same, refer-v encc being had to the accompanying drawings', frml ing part 0I' this specification.'

Fignrel is a vertical section of my improvedcoolei',

taken through the line :1: x, Iig. 2.

Figure 2 is a horizontal section of the same, taken through the line yy, iig l.

Figure 3 is a detail sectional view, taken through tom tothe top of I the cooler, and the space between them is lled with powdered charcoal or some other suitable non-conducting material.

The space between the inner wall O and the middle wall B should be greater than that between the walls A and B, so as to form a receptacle of snihcient caf pacity to contain the water to be cooled.

. The inner wall C does not extendV to the bottom, D,

as shown in fig. 1, and is provided with two bottoms, E and F, at a shoit distance from each other. The upper bottom,'F, is provided with ianges G, projecting downward nearly to the bottom, E, leaving only space between their lower edgeslan'd the bottom, E, for'the free passage of the water to be cooled.

The space between the .walls B and Gris also provided with a bottom, H, which is placed ailittle lower than thel bottom, F, so as to lea'v'e space for openings in the wall O ,lbetwee'n the bottom, F, and the bottom, H, for the passage of the -water-to be cooled from 'the space between the walls B and O to the space between the bottoms E and F.

The space within the wall C is designed to receive the ice, the waste waterii'oin which passes down through the pipe I to thespace below the bottoms E and H, which said space is designed to be of such a size as to contain all the water ibrmedby the melting of all the ice that can be put into .the space within the wall C above the bot-tom, F.

The water to be cooled may be introduced through the short pipe J in the top of the cooler, o r the cooler may be connectedwith a water-pipeby means of the short pipe K, leading inv through the walls A'B, as shown in iigs. 1 and 2.

' he cooled wateris diawn out fromv the space between the bottoms E and F, through the pipe L, and thewaste water lformed from the melting ice is drawn out-through the pipe M.

The pipes L and M are provided with stop-cocks in the ordinary manner.

When the cooler is to be used for cooling milk and similar substances, the milk or 'other substance to be cooled isfpla'ced in the space within the inner wall C, and when cooled or required for use, is drawn oifthrongh a -pipe leading out from the said space or chamber just above the bottom, F, as 'shown in red lines in figs. 1 andl 2. In .this case,-.the.upper oriice of the pipe I should be closed with a cork or other secure and easily-detaohable stopper, as is also shown in red lines in iig. 1.

In this case, the ice is placed in the receiver N,.which is removably secured to(y the inner wall G, by means of the arms or pins a, attachedto the body a2 of the receiver N. From the bottom of the body 'a2- ofthe receiver, three pipes, n3, lead intothe receptacle a4, coniiected with the said body n2 by the said pipes n. The receptacle a4 is provided with anges projecting downward from its'botto'm, as shownin fig. l.

The object ofthe iianges G and a is to present a greater cooling-surface to the'liquids to vbejcooled.

When the ice in thereceiver N has become melted,

the Waste water may be poured out by removing the" said receiver' N; or ifzthe cooled liquids have iii-st been diawn'oii'the wastewater may be poured out' by inverting the entire cooler.

O'is a removable cap or cover,covering thespace withinthe wallO, and which is also provided with a downwardly-projecting ange fitting into the mouth of the receiverN, as shown in fig. 1.

Having thus described my invention,- I claim as new, and desire to secure by Letteis Patent-4 1. lThe combination of the walls A B C, bottoms D, E, F, and H, flanges G, pipe I, pipes L M, provided with stop-cocks and ingress-ppesJ K, either-'or both with each other, said parts being constructed and ar-- ranged substantially as herein shown land described, and for the purposes set forth.

,2. The receiver N a" n3 n" n5, constructed substanwith iianges G, -substantially as herein shown and described, and for the purpose Vset forth.

The above specification Of-my invention signed by me, this lstnday of October, 1.868. HERMAN PIETSOH. Witnesses:
